A plication filed October 5, 1926. Serial No. 139,702.

The invention relates to the heating of motor vehicles propelled by means of an internal combustion engine embodying a water cooling j acket and a radiator included in the cooling system.

The invention contemplates a heater of any make, connected with the water cooling system to utilize the hot water as a heating medium, and a valve of novel structural formation for controlling thecirculation of the hot water for shunting it through the heater when it is required to warm the car or other desired place.

The invention provides a valve, embodying a casing having two chambers and openings, and a plug within the casing having a limited rotary movementand formed with passages for directing the hot water in its travel as required, according to the adjusted position occupied by the plug which is operable from the drivers seat at will. I

WVhile the drawings illustrate a preferred embodiment of the invention, it is to be undertsood that in adapting the means to meet specific needs and requirements, the design may be varied and such other changes in the minor details of construction may be resorted to within the scope of the invention as claimed, without departing from the spirit thereof.

For a full understanding of the invention and the merits thereof, reference is to be had to the following description and the drawings hereto attached, in which,

Figure 1 is a fragmentary side view of an internal combustion engine and radiator illustrating the application of the invention. Figure 2 is a vertical, central sectional view of the valve on a larger scale and showing the position of the plug when adjusted to shunt the hot water through the heater.

Figure 3 is a horizontal section on the line 33 of Figure 2.

Figure 4 is a horizontal section on the line.l4 of Figure 2. V

Figure 5 is a sectional view on theline 55 of Figure 3, looking in the direction of the arrows.

Figure 6 is a horizontal sectional view similar to Figure 3 showing the plugadapted to cut off the flow of water from the heater and establish a'direct passage tothe radiator, and

Figure 7 is a detail perspective view .ofthe :plug.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters. l

The numeral 1 designates the block of an internal combustion engine h-aving'tlie usual water jacket for'cooling the cylinders- The pump tor creatinga' positive circulation of water is indicated at 2, and ,3 represents the usual radiator through which the Water passes to be cooled prior to its return to the water jacket in a cycle of operation.

The valve constitutes the essential feature of the present invention and is interposed in the connection between the radiator and the box 10 provided at the top of the casing 4 in line with the center ofthe chamber 7. The valve plug 5 is formed with adiametrical open ng 11 and a lateral opening 12. These openings are in the same plane and communicate. The valve plug has a side portion cut away, as indicated at 13, to provide an opening or passage for the return of the shunted water. The opening or passage 13 is in a different plane from the intersecting openings 11 and12. An end portion of the plug is cut away to provide a stop shoulder 14 and a screw 15 threaded into an opening formed in the end of the casing acts jointly with the shoulder 14 to limit the turning of the valve plug in each direction. In one position of the plug the water from thejacket of the engine has a direct passage through the radiator. In the other position of the valve plug the water is shunted and caused to pass through the heater, not shown, be

fore entering the radiator and returning to 'in Figure 6, the water from the jacket of the engine has a direct passage through the Valve to the radiator 3. In this position of the valve the water is cut oif entirely from the heater. Other openings of the valve casing 4 are designated by the numerals i and 21 and are in different planes, the open- 'ing 20 being in the plane of the opening 18 of'the casing and the openings 11 and 12 of the plug valve 5. The opening 20 constitutes the passage for the outflow of the water from the valve to the heater, when the valve 5 is in the position shown .in the several views with the exception of Figure 6. The opening 21 is in position to register with the cut away portion or opening 13 of the valve plug 5, as shown most clearly in Figures 1 and 5. When the valve plug 5 is turned to cut off the direct flow through the openings 18, 11 and 19 the opening 13 registers with the opening 21 and the chamber 8. The water on its return from the heater enters the opening 21 and passes through the opening 13 into the chamber 8 and out from .the chamber or by-pass 8, through the opening 19 to the radiator. The two extreme positions of the valve plug 5 are indicated most clearly in Figures 3 and 6. Obviously, the valve plug may be turned part way so as to shunt a portion of the water only through the heater when it is not required to obtain the maximum amount of heat. The opening 21 constitutes the return for the water shunted through the outflow 20.

In the preferable construction of the valve the chambers 7 and 8 are bored into the easing from an end thereof, and a plate 22 is bolted to the casing closing the open ends of the chambers. The valve is located in the length. of the connection 23 between the radiator 3 and the outlet of the water jacket. Pipes 24 and 25 connect the valve casing with the heater, not shown, and may be of any construction. When metal pipes are employed, the ends coupled to the valve casing may be flanged outwardly and clamped thereto by collars 26. Then the collars 26 are loosened, the pipes may be turned to any adjusted position and are made secure by tightening the collars by screwing home the bolts or other fastening means employed for connecting the collars to the valve casing. When the valve plug 5 is turned to shunt the water through the heater, the flow is as follows: from the water jacket into the valve casing, through the inlet 18, thence through the openings 12 and 11 into the outflow 20, 7

through the pipe 2st to the heater, not shown, thence out through the pipe 25 into the valve casing through the opening 21, thence through the opening 13 into the chamber, or by-pass 8, and out through the opening 19 to the radiator 3 through the connection l/Vhen the heater is not required, the valve plug 5 is turned to cut off the outflow 20, thereby bringing the diametrical opening 11 of the valve into registering position with the inlet 18 and the outlet 19, thereby establishing a direct passage for the water through the valve to the radiator. The several openings and passages are of a uniform size corresponding approximately to the passage through the connection 23, so as to offer a minimum resistance to the flow of the water.

The invention is adapted for general use in connection with water cooled engines including a radiator in the water circulation, thereby admitting of the water being shunted so as to be utilized for heating purposes, the arrangement being such as to insure a circulation of the water through the heater and radiator, when required, or through the radiator only when the heater is not required to be used.

Having thus described the invention, I claim:

1. In a water cooling system for internal combustion engines, including a radiator, a valve interposed in the connection between the radiator and water cooling jacket of the engine, the same comprising a casing having a valve chamber, a by-pass in communication with the valve chamber, a direct inlet, a direct outlet, an outflow and a return, and a movable valve member within the valve chamber and provided with openings which in one position of the valve admit of a direct flow of the water through the inlet and the outlet, and which, in another position, of the valve shunt the water to cause it to pass from the casing through the outflow and back through the return and by pass before discharging through the said outlet.
